1. Field of the Invention
The subject matter disclosed relates to a locator that can physically locate an electronic device such as a phone or computer in a communication network.
2. Background Information
Most commercial offices are configured to allow a plurality of computers to be connected to one or more servers in a network. The network may include a local area network (LAN) and/or a wide area network (WAN). The computers are typically linked to the network through a data port that is physically connected to a number of routing wires. Each computer has an associated network address. Each data port has an associated physical address. The network will typically have a router(s) and hub that route information directed to the network addresses of the computers to the appropriate physical addresses of the data ports.
Some computers also have modem boards that are connected to voice ports of a telephone network. Each voice port has a unique phone number to allow routing of incoming information transmitted through the phone network. The telephone network will typically have switches to route phone calls to the appropriate voice ports.
The server of the network may have a software program that allows an operator to correlate the network address of the computer with the physical address of the data port. This correlation allows the network router and hub to route information to the appropriate computer. Likewise, the switch(es) of the telephone network may have a software program that allows an operator to correlate a phone number with a particular a physical cable number associated with the voice port.
Commercial entities will periodically move employees to different office locations. This typically requires moving the employee's computer. Each time a computer is moved to a different location an operator must re-configure the server and/or phone switches to correlate the computer with the new data and voice port locations. Re-configuring the network is time consuming and adds to the cost of moving the employees. Additionally, the employee is unable to move the computer without seeking the assistance of an operator to re-configure the network. This limits the mobility of the employees and their computers. It would be desirable to provide a system and method that allows an end user to plug a computer into a network and have the network automatically re-configured without any operator assistance.
9-1-1 emergency systems are typically operated independent from public telephone systems. 9-1-1 systems do not have the capability to correlate phone numbers with physical locations of the caller, especially if the call is being routed through a packet switched network such as VOIP. Packet switched networks route in accordance with network addresses which have no relationship to the physical location of the equipment. Consequently, a caller who is unable to communicate their physical address may not receive 9-1-1 assistance. The caller may be located at a large commercial building or campus so that even a street address may not properly convey the exact location of the caller. For example, the caller may be located at a building with multiple offices and floors. The caller may give the 9-1-1 service a street address and nothing more. The service provider, such as an ambulance service, must then figure out where the caller is physically located in the building. It would be desirable to provide a system that would allow a 9-1-1 service to readily locate the exact physical location of a caller.
Large commercial entities typically have a large number of computers, phones, printers, etc. which will be referred to as assets. To date there is not a practical system or method for keeping track of the existence and/or location of such assets. Asset management can be an important criteria particularly when the entity is trying to account for such assets. It would be desirable to provide an asset management system that can account for the existence and location of electronic assets such as computer, printers, etc.
A repeater that can locate an electronic device in a packet switched network. The repeater stores a physical address that corresponds to a physical address of the electronic device. The electronic device includes a device identification that can be read by the repeater. The repeater transmits the stored physical address and the device identification to a server. The server contains a relational database that correlates the device identification with the physical address.

Referring to the drawings more particularly by reference numbers,
The computer 10 may include a plurality of integrated circuits 22 mounted to a printed circuit board 24. The integrated circuits 22 may be connected to an electrical connector 26 that is attached to the board 24. The connector 26 may mate with one of the connectors 14 of the backplane 12. The printed circuit board 24 may also be connected to a hard disk drive 28. The hard disk drive 28 is coupled to the integrated circuits 22. The printed circuit board 24, integrated circuits 22 and hard disk drive 28 may all be enclosed by an outer housing 30. The outer housing 30 may have an opening 32 to allow the connectors 26 and 14 to mate.
The system 14 may include a mechanical lock 34 that is mounted to the structure 20. The lock 34 can be actuated to secure the computer 10 to the backplane 12. By way of example, the lock 34 may be a solenoid actuated plunger 36 that moves into a corresponding slot 38 the housing 30. The plunger 36 can be moved out of the slot 38 to allow the computer 10 to be pulled out of the backplane 12.
The I/O interface-56 is connected to the connector 26. The microprocessor 52 may be connected to a graphics controller that is integrated with other functions such as bus management in an integrated circuit commonly referred to as a chip set 58. The microprocessor 52 may also be connected to a secondary I/O interface 60. The secondary I/O interface 60 can be coupled to an external device such as additional memory (not shown).
The computer 10 may also have a transmitter 62 that can wirelessly transmit signals. By way of example, the transmitter 62 can transmit signals at radio frequency (RF) The transmitter 62 may be coupled to a non-volatile memory device that contains an RF id. If the computer 10 is not properly shut down and detached from the backplane 12, the transmitter 62 may then automatically transmit the RF id on a continuous or periodic basis. For example, the computer 10 may require a password or biometric entry to properly shut down and remove the computer 10. If the password/biometric is not properly entered and the operator pulls the computer 10 out of the backplane 12 the processor 52 may cause the transmitter 62 to emit the RF id. The computer 10 would have a battery (not shown) to provide power to the transmitter 62.
The backplane 12 may have an I/O interface 64 that is connected to I/O ports 66, 68, 70, 72 and 74. Each I/O port 66, 68, 70, 72 and 74 is connected to a corresponding electrical connector. The I/O interface 64 is also connected to a connector that can be mated to the computer 10.
The I/O ports 66, 68, 70, 72 and 74 can be connected to external devices that communicate with the backplane 12 using different signals and different protocols. The interface 64 may contain the protocols required to transmit information through the ports 66, 68, 70, 72 and 74. The ports 66, 68, 70, 72 and 74 may have circuits to drive the signals to interface with the physical layer of the external device.
By way of example, I/O port 66, may be connected to a monitor 76. The I/O interface 64 and port 66 can be configured to transmit signals from the computer 10 in accordance with signal levels, protocols required to drive the monitor 76. The I/O interface 64 may include a hot plug firmware routine that determines the protocol, signals required to drive the monitor 76 through a series of handshake signals transmitted between the devices 64 and 76.
I/O port 68 may be connected to a keyboard 78. The interface 64 and port 68 may be configured to provide protocols and signal levels which allow information to be transmitted from the keyboard 78 to the computer 10.
I/O port 70 may be connected to a network 80. The network 80 may be connected to a server 82. By way of example, the I/O port 70 may include integrated circuits that transmit signals in accordance with an Ethernet standard.
Information may be transmitted through the network 80 in accordance with a Transmission Control Protocol/Internet Protocol (TCP/IP). I/O port 72 may be connected to a telephone network 86. The telephone network 86 may be a plain old telephone system (POTS), a public switched telephone network (PSTN), Integrated Service Data Network (ISDN), Digital Subscriber Line (DSL) or any other phone service. The interface 64 and port 72 may transmit information in accordance with the signal levels, frequencies, protocols, etc. of the telephone network.
I/O port 74 may be an open port for additional devices. For example, port 74 may support Universal Serial Bus (USB) protocol. The backplane 12 may have additional ports that support other post, present and future protocols and physical layer specifications. The I/O interface 64 may also be connected to the lock 34 by lock driver 86.
The backplane 12 may have a memory device 88 that is connected to the I/O interface 64. The memory device 88 may be non-volatile memory such as an EEPROM. The memory device 88 may include a backplane identification. The backplane identification is unique to the backplane 12.
By way of example, there are typically a plurality of backplanes 12 connected to the networks 80 and 86. Each backplane 12 will have a different backplane identification. The backplane identification may be a series of alphanumeric characters. The backplane identification may also be encrypted.
The computer 10 may store a unique client identification. The client identification may include personal information of the computer end user. The personal information may include a network address and telephone number for the computer. The client identification may be encrypted or otherwise encoded. The client identification may be stored in at least one hidden sector of the hard disk drive, to prevent unauthorized access to the client ID.
The server 82 may also be connected to the telephone network 86, an alarm 89 and a receiver 90. The receiver 90 can be adapted to receive the signal emitted by the transmitter. 62 of the computer 10. The alarm 89 may include an audio and/or visual indicator such as a speaker and LCD display, respectively.
The network 80 may include routers and hubs (not shown) that route information to the computer 10 in accordance with a network address. By way of example, the network address may be an Internet Protocol (IP) address. Likewise, the telephone network 84 may switch information to the computer 10 in accordance with a telephone number.
As shown in
The server 82 may operate in accordance with a software routine that accepts a command from the computer 10 and re-configures the networks 80 and 84 in accordance with the command. For example, the command may include the client identification and an instruction to re-configure the networks 80 and 84. The server 82 will then correlate the backplane identification and evacuation plan with the network address and phone number associated with the client identification. The server may include a look-up table that associates the client identification with a network address and phone number. The server 82 can then vary the network relational database to correlate the address and phone number of the client ID with the backplane that is mated with the computer. Once the networks 82 and 84 are re-configured all information associated with the address and phone number of the computer 10 will be routed to the appropriate backplane. The computer ID automatically re-configures the network(s) by transmitting a command. There is no requirement to manually re-configure the system.
The server 82 may also have a software routine that compares the client identification with an authorized client identification and activates the alarm if the identifications do not match. The server 82 may also send a command to the backplane 12 to drive the lock into a locked position so that the end user cannot unplug the computer 10 from the backplane. The server may also inhibit operation of the computer. For example, the server may send a command(s) to turn off the computer 10, or prevent communication through the backplane 12.
The transmitter 62 may transmit the RF id if the computer 10 is improperly detached from the backplane 12. The RF id signal is received by the receiver 90. The server 82 may have a software routine that drives the alarm 88 and records the alarm event when the receiver 90 senses the RF id.
The microprocessor 52 may operate in accordance with a software routine. The software routine may be performed in accordance with instructions and data stored within memory 54 and/or the hard disk drive 28.
The end user initially plugs the computer 10 into the backplane 12. The computer 10 then reads the backplane identification from the memory device 88 in process block 200. The backplane ID can be read during an initialization routine of the computer 40, wherein the processor 52 request data from the appropriate address(es) of the backplane memory 76. In decision block 202 the computer 10 compares the backplane identification transmitted from the backplane with a stored backplane identification. The stored backplane identification is the backplane ID for the backplane that was last coupled to the computer 10. If the identifications match, a boot up routine is run so that the computer 10 can be operated in process block 204. Matching IDs signifies that the computer 10 has not been moved to a different backplane.
If the identifications do not match, the computer transmits a command to the server in block 206. The command may include the client identification. The client ID may be retrieved from the hidden sector(s) of the hard disk drive 28.
The command may be routed to the server in accordance with a server network address entered into the computer through a configuration program. Alternatively, the server may download the network address when the computer 10 is plugged into the backplane 12. The backplane 12 may send a signal to prompt a download of the server network address when the connectors 14 and 26 are mated. The server then correlates the client identification information such as network address and phone number with the backplane identification in block 208. All information addressed to the network address and/or phone number will then be routed to the corresponding backplane associated with the client identification.
The server may compare the client identification with an authorized client identification in decision block 210. If authorization is not granted the server may transmit a command(s) to the backplane to inhibit operation of the computer and/or engage the lock in process block 212. If authorization is granted the server may then transmit a evacuation plan 214 to the computer 10. The evacuation plan may include diagrams, etc. that show the end user an evacuation route from the facility. The evacuation plan is unique to the backplane, such that the evacuation route is specifically directed to the physical location of the backplane. The computer 10 can be booted subsequent to the transmission of the command in step 206.
The present invention thus provides a system and method to automatically re-configure a network when a computer is plugged into a backplane.
While certain exemplary embodiments have been described and shown in the accompanying drawings, it is to be understood that such embodiments are merely illustrative of and not restrictive on the broad invention, and that this invention not be limited to the specific constructions and arrangements shown and described, since various other modifications may occur to those ordinarily skilled in the art.
The phone switch 252 may have a relational database 264 that has a phone cable number field 266 and a phone number field 268. When the computer 10 is plugged into a different backplane both relational databases 254 and 264 are updated to correlate the network address and phone number of the computer with the physical cables attached to the backplane. This embodiment is similar to the embodiment shown in
Although a technique is described wherein the computer does not send a command until the backplane ID does not match a stored backplane ID, it is to be understood that the system may operate in another matter. For example, the computer may automatically send the command to configure the relational database each time the computer is mated with the backplane and/or every time power is turned onto the system.
Likewise, although a system is described wherein the computer 10 transmits the command, it is to be understood that the backplane 12 can be constructed and configured to read the stored backplane ID in the computer 10 and then send the re-configuration command. By way of example, the backplane 12 may include a digital signal processor (DSP) that performs one or more steps to re-configure the database.
The network 406 may be connected to a server 408 that contains a relational database. Although a server 408 is described, item 408 may be any device that can store a relational database.
The outlet box 404 may include one or more female connectors 410. By way of example, the connectors 410 may be a RJ-11 or RJ-45 device. The locator 400 includes a corresponding connector 412 that can be plugged into the outlet 404. The locator 400 will also have a female connector 414 that will receive a corresponding male connector 416 coupled to the phone 402. The connectors 412 and 414 may be attached to a locator housing 418. By way of example, the housing 418 may be constructed from a molded plastic material. The housing 418 may include a mounting ear 420 to allow the locator 400 to be mounted to the outlet box 404 by a fastener 422.
The locator 400 may include a power port 424 that can be connected to an external power source (not shown). The external power source may be required to power the internal circuits of the locator 400. By way of example, the external power source may include a transformer, rectifier, etc. that is commonly used to convert AC power to DC power for use in integrated circuits. Although a power port 424 is shown and described, it is to be understood that the network 406 may provide power to the locator 400 through the connectors 410 and 412.
The locator 400 may include one or more additional connectors 426 attached to the housing 418. The connectors 426 can be attached to additional external devices (not shown). By way of example, the connectors 426 may be universal serial bus (USB) devices. The USB connectors can be connected to devices that support USB protocol such as computers and printers.
Although a processor is shown and described, it is to be understood that the locator may have other logic circuits that perform the required functions. For example, the locator may have programmable logic such as decoders, etc. to perform the required functions.
Although a separate locator plugged into an outlet box is shown and described, it is to be understood that the locator can be integrated into an outlet box. It being understood that a separate locator module will be required to retrofit existing outlet boxes to include the locator function. New outlet boxes may contain the locator circuits etc. that are then mounted into building structures. Likewise, although the locator is shown mounted to the outlet box, the locator may be connected to the box by an intermediate telephone cord.
In block 502, the user enters a start code to indicate that the following information will be data to be stored in memory of the locator 400. The start code should be a sequence of alphanumeric characters that will not be used to dial a phone number of telephonic operate a remote system such as a voice mail or a voice messaging system.
In block 504, the user enters the physical location of the outlet through the phone keypad. For example, if the user is at a commercial building, they may enter an address of “Building A, floor 4, column 3, 123 Main Street, Sparkle City”. The user may also enter the phone number of the device. The address and phone-number are stored in memory 432 of the locator 400. The locator 400 may also have a locator address stored in memory 432 that is unique for each locator unit.
In step 506, the user enters an end code that indicates that the data has been completed. The end code may also cause the locator to transmit the physical address, locator address and phone data over the network to the server 408. The relational database of the server 408 then stores the data so that the phone number is correlated with the physical address and the locator address. A subsequent call by the user can be detected and correlated so that the recipient can readily determine the callers physical address.
For example, the caller may place a 9-1-1 emergency call through the phone device 402. The caller may be unable to tell the 9-1-1 service their address, or the caller may give an address to a large commercial building without identifying their specific location within the building. The emergency service will be able to determine the exact physical location of the caller from the relational database which correlates the phone number with the physical address (e.g. column 3, floor 4 of Building A). The database may also include additional information such as the age, height, weight, past medical history, etc. of the caller. This information could also be retrieved from another database through a call routine of the relational database.
It may be desirable to encode the physical address data with the locator address data to prevent unauthorized access to the data and to prevent “prank” 9-1-1 calls. The data may be encoded by combining and/or blending the physical address data with the locator address data.
Although the process is described so that the locator 400 transmits the data upon entry of the end code, it is to be understood that the data may be stored in the locator memory and only transmitted upon a subsequent 9-1-1 entry. Additionally, although transmission of the locator address is described, it is to be understood that the locator may only transmit the physical address and phone number.
As yet another embodiment, the locator 400 may transmit the physical address stored in memory every time the caller dials 9-1-1 or some other predefined number. Thus the emergency service will get the physical address of the caller each time they call 9-1-1.
The USB ports 426 allow the locator 400 to also become an asset management device. The controller 430 may read information from each device that is plugged into a UBS port. For example, a computer and a printer may be plugged into separate UBS connectors of the locator 400. The computer will typically have a phone and/or network card connected to the locator UBS port. The locator 400 may read the MAC address of the computer network card and the printer and then retransmit this information to the server along with the physical address and/or locator address. The server may contain a database that lists the existence and the physical location of each device. This allows a proprietor of the devices to readily keep track of its assets. The asset manager locator function could work the same or similar to the computer/backplane system described and shown in
As an alternative, the database may have a wire map relational database that correlates individual outlets with the physical address of the outlet. The locator could then provide a locator address that is transmitted to the server and is correlated with the specific physical address by the database. When a device is plugged into a locator connector, the locator transmits a message that includes the device ID and the locator address data, without physical address data. The relational database can then correlate the device ID with the physical address. The asset management function may be separate or in combination with the 9-1-1 function of the locator.
The locator may also function as a gateway that is coupled to a number of monitoring devices. For example, the locator may be connected to an electric utility meter, gas utility meter, gas leak detector, smoke detector, burglar alarm. The locator may transmit information to a remote site that relates to the functions of these devices. For example, the locator may transmit power usage data, physical address data and/or locator address data to a remote site.
It is generally understood that once installed, the locator 400 is not physically removed from the outlet box on which it is connected. Therefore, even though the user may change phones, computers, etc., the physical address of the locator is always the same. The locator creates a permanent electronic physical address. This allows for improved 9-1-1 service, asset management and household monitoring.
A server 606 may be coupled to the repeater 600 through the packet switched network 604. It is to be understood that the server 606 may be coupled directly to the repeater 600 without the packet switched network connection. The server 606 contains a relational database 608 with fields 610 and 612 that correlate device identifications with physical addresses.
The repeater 600 may contain a wire map 630 that maps the output ports with specific physical address locations. For example, if the repeater 600 is a hub a plurality of RJ-45 electrical outlets (e.g., see outlet box in
In one method of operation, an electronic device 602 is plugged into an electrical outlet. For example, a phone or computer is plugged into an RJ-45 outlet. The electronic device 602 may then transmit data to the repeater 600 to be retransmitted to the packet switched network 604. The data may include a device identification such as an IP address or a MAC address. The repeater circuit 620 parses the data to read the device identification. If the device identification to that particular output port is new (e.g., does not match the ID in the wire map 630), the repeater circuit 620 may remap the wire map 630 to correlate the new device ID with the output port that received the data. The repeater 600 can transmit the device ID and the physical address location to the server 606, either automatically or in response to a request from the server. The server relational database 608 then correlates the physical address with the new device ID. The repeater 600 may update the server 606. The repeater 600 may also transmit a phone number associated with the device 602 to the server 606. The phone number is mapped to a corresponding field of the relational database 608. The repeater 600 and/or server 606 may have the same or similar functions as the embodiments described and shown in
